Theoretically the idea behind therapy seems to be one can, may and should tell the therapist anything they want. It is the line those guys tout the most. It is the big selling point they tell all the clients.

Realistically, in practice, I have never found it such that those guys are competent enough or mentally equipped to hear anything or everything from a client. More like when cell phone companies say you are buying unlimited data but really it is only 20 gb (or whatever - just an example) - Taking such a statement literally leads to disastrous results for the client in my opinion.
